Denso Spark Plug FK20HBR11 (90919 - 01249) - 4 Spark Plugs

Iridium Power is recommended for drivers who care about:

• Performance
  By using a 0.4mm diameter iridium alloy centre electrode and a special ground electrode, Iridium Power realises spark performance unseen until now. It steadily gives a high level of response under a variety of driving conditions. The result? Increased acceleration and torque compared to regular plugs.
• Mileage
  If you use your car on a daily basis, you may be concerned about fuel consumption. Iridium Power is one solution. Even during idling ignition is assured, with less fuel consumption and less noise. The good ignitability from the fine electrode (0.4mm) of Iridium Power draws out much more performance from the engine.
• Horse Power
  Iridium Power has a low required voltage and a high ignitability, resulting in less misfiring and no spark, the outcome being a dramatic improvement in combustion. Engine output is therefore increased.
• Acceleration
  Iridium Power best demonstrates its performance improvement during acceleration. Iridium Power has a 0.4 mm diameter iridium centre electrode and a specially shaped ground electrode. These features combine to achieve higher ignitability and require lower spark voltage than ever before. This enables high-response driving with fewer misfires than under higher required voltage spark conditions, and fewer misfires when ignitability is difficult. As a result, acceleration improves in comparison with normal plugs.
